Description: This star garnet is a facet grade garnet. When cabbed, the star is created (if orientated correctly).

Star garnet is a unique variety of garnet that is found primarily in Idaho, USA. It is known for its striking appearance, featuring a six-pointed star pattern that appears to shimmer on the surface of the gemstone when viewed under certain lighting conditions.

The star garnet was first discovered in the late 1800s in the Idaho panhandle, specifically in the Emerald Creek area near the town of St. Maries. Today, the majority of the world's supply of star garnets still comes from this region, although smaller deposits have been found in other parts of Idaho and in other countries such as India and Sri Lanka.

The star pattern in the garnet is caused by the presence of inclusions within the stone, typically microscopic fibers of the mineral rutile that are arranged in a hexagonal pattern. When light passes through the stone, it is refracted by these inclusions, creating the distinctive star pattern that makes the gemstone so prized.

Star garnets are typically cut in a cabochon style to enhance the star effect, and are often used in jewelry such as rings, necklaces, and bracelets. They come in a range of colors, including deep red, burgundy, and purple.

Star garnets are a unique and beautiful gemstone that have become synonymous with the state of Idaho. They are a popular choice for those seeking a one-of-a-kind gemstone with a rich history and stunning visual appeal.
